Manga Dungeon Builder: The Demon King’s Labyrinth is a Modern City!

Demon Lords are incredibly powerful creatures that are able to control monsters and demons, erect and rule huge labyrinths. At the same time, the Demon Lords constantly tempt people to enter these labyrinths in order to go in search of treasures. In fact, these Masters most of all wanted to feed on human despair, because they could not escape. However, one Demon Lord decided that he would not feed on people's despair, but decided to feed on their positive emotions. To do this, he erected a happy city instead of a terrifying labyrinth. Well, history will tell us a lot more about such an eccentric Demon Lord and his desires.
